DOUALA (Reuters) -Hundreds of opposition supporters barricaded roads and burned tyres in Cameroon's commercial capital on Sunday, as protests intensified a day before the announcement of presidential election results.
Police fired teargas and water cannon to break up the crowds of supporters of opposition candidate Issa Tchiroma. They say he beat veteran leader Paul Biya in the October 12 vote and have accused authorities of preparing to rig the election.
